Suppose that 14 children who were learning to ride two-wheel bikes were surveyed to determine how long they needed to use training wheels. It wasrevealed that they used them an average of 6 months with a sample standard deviation of 3 months. Assume that the underlying population distribution isnormal. Which of the following correctly defines the random variable ?O A.- is the average time that all children will need to use training wheelsO B. - is the time that all children will need to use training wheelsOc.is the underlying normal distribution for the populationO D.- is estimated with the sample statistic of 3 monthsO E. - is the average time that the 14 children needed to use training wheels

The variable x is the number of times that the 14 children needed to use training wheels.

Answered: Suppose that 14 children who were…

Students preparing for comprehensive exams usually spend many hours studying. Suppose it is known that the time students spend studying for comprehensive exams has a distribution that is skewed heavily to the right with a mean of 41.3 hours and a standard deviation of 6.8 hours. If a simple random sample of 72 students is selected and the amount of time each spent studying for the comprehensive exam is determined. State and check the two assumptions.

What is the standard deviation of the sampling distribution of the sample proportions of health-care workers having bacteria on one or both hands? A. 100 B. 0.0462 C. 0.69
A sample of values taken from a normally distributed population are 6.8, 7.2, 5.4, 8.8 and 10.2. If the standard deviation of the population is 2.1 determine the range of the sample values within which the mean of the population has a 95% probability of lying.
A Two-Sample Hypothesis TestThe mean number of English courses taken in a two-year time period by male and female college students is believed to be about the same. An experiment is conducted and data are collected from 29 males and 16 females. The males took an average of three English courses with a standard deviation of 0.8. The females took an average of four English courses with a standard deviation of 1.0. Are the means statistically the same? (Assume a 5% level of significance.)Useful tools:Normal Distribution Calculatort-Distribution Calculator 1. Which of the following null and alternative hypotheses match this scenario?

Fast-food restaurants spend quite a bit of time and money studying the amount of time cars spend in the drive-through. In 2007, QSR Magazine studied drive-through times at fast-food restaurants, and Wendy's had the best time, with a mean time of 138.5 seconds with a standard deviation of 29 seconds. Assuming that the data was normally distributed, use R to answer the following: Find the probability that a randomly selected car gets through Wendy's drive-through in less than 100 seconds. а) Find the probability that a randomly selected car gets through Wendy's drive-through in over 3 minutes... b) c) Find the probability that a randomly selected car in at the drive-through from 2 to 3 minutes. If Wendy's has 350 cars go through the drive-through in one day, how many of these cars were in the drive-through between 2 and 3 minutes? d) e) What drive-through time represents the cut-off for the lowest 25% of times (the bottom quartile)? f) Suppose that Wendy's wants to institute a policy…
